Historic (pre-2007) gage-height data may contain erroneous values, such as pressure sensors encased in ice, even if they are flagged as approved. These data are made available to the public, but data users are cautioned to carefully screen the data and contact the USGS Kansas Water Science Center if they have questions or concerns about specific values.
! Statistics pages will be decommissioned in early 2026. Please find the modernized pages in WDFN that suit you best. Learn more about our modernization plans and timeline.
